ELEKTRO-MAGNETISCH ANGETRIEBENER SCHWINGSPIEGEL.

摘要

The minor has a drive system which porvides a drive force directly proportional to the supplied current, which may be digitally controlled in a microprocessor. The drive system uses a permanent magnet (4) lying between a pair of electric field coils (5a, 5b) with respective iron cores (6a, 6b). The effected movement is delected via associated linear tachogenerators and displacement sensor for feedback regulation allowing a required oscillation function to be obtain obtained.
